Matsya Purana — Dynastic Genealogies: Paurava–Anu Lines
बलेश्च ब्रह्मणा दत्तो वरः प्रीतेन धीमतः महायोगित्वमायुश्च कल्पस्य परिमाणकम् //
baleśca brahmaṇā datto varaḥ prītena dhīmataḥ mahāyogitvamāyuśca kalpasya parimāṇakam //
And to Bali, the wise Brahmā—being pleased—granted a boon: supreme yogic mastery, and a life-span enduring for the full measure of a Kalpa.
It frames Purāṇic cosmology through the unit of a Kalpa, implying that beings can receive boons lasting across vast cosmic cycles that encompass creation, maintenance, and dissolution phases.
Indirectly, it highlights the Purāṇic ethic that divine favor follows merit and discipline: yogic mastery and long life are portrayed as fruits of spiritual excellence, encouraging rulers and householders to uphold dharma and self-restraint.
No direct Vāstu or temple-ritual rule appears in this verse; its technical focus is cosmological time (kalpa) and yogic attainment, which can contextualize long-duration vows and ritual timeframes in Purāṇic practice.
